BACKGROUND 1. Technical Field

This invention relates to a package structure and a manufacturing method thereof, in particular, to a semiconductor package structure with an electromagnetic interference shielding function and a manufacturing method thereof.

2. Description of Related Art

Electromagnetic interference (EMI) can propagate as current along current-carrying conductors such as power lines and cables, or through space as electromagnetic waves. Therefore, according to the different coupling paths of electromagnetic interference, electromagnetic interference can be divided into two types: conducted electromagnetic interference and radiated electromagnetic interference. Electromagnetic interference transmitted through current-carrying conductors is called conducted electromagnetic interference, and electromagnetic interference transmitted through space is called radiated electromagnetic interference.

In general, for radiated electromagnetic interference, spatial shielding or isolation is usually adopted as a countermeasure for improvement, which is divided into the use of metal covers or wire bonding to shield electromagnetic interference, which will be described below.

Please refer to FIG. 1 , a conventional package structure 10 includes a circuit board 11, a chip 12, and a packaging layer 13. The chip 12 is electrically connected to a surface of the circuit board 11 and covered by the packaging layer 13. The circuit board 11 can be a multi-layer circuit board, which has a plurality of circuit layers 111 stacked to each other and encapsulated in a dielectric layer 112. The stacked circuit layers 111 are electrically connected through conductive through holes or conductive vias, and one of the circuit layers 111 is designed as a grounding layer 111 a.

In order to prevent the chip 12 from being affected by radiated electromagnetic interference, the first EMI shielding method uses a metal cover 14 to cover the outside of the package structure 10 to isolate external electromagnetic interference. The metal cover 14 has a top cover 141 and a sidewall 142. The top cover 141 covers the chip 12, and the sidewall 142 is electrically connected to the grounding layer 111 a on the side edge of the package structure 10 to ground the metal cover 14, thereby achieving the purpose of the EMI shielding.

Then, refer to FIG. 2 , a conventional electronic device 20 includes a circuit board 21, a plurality of chips 22, and a plurality of passive components 23. The chip 22 and the passive components 23 are soldered on the surface of the circuit board 21.

In order to prevent the chip 22 from being affected by radiated electromagnetic interference, the second method of EMI shielding uses wire bonding to cover the chip 22 to isolate external electromagnetic interference. The wire bonding to cover utilizes a plurality of copper wires 24 to span over the chip 22 to form a cover. The two ends of each copper wire 24 are electrically connected to the ground pads of the circuit board 21, and the ground pads are electrically connected to the exposed electrical connection pads of the grounding layer of the circuit board 21 to form a partial or a full EMI shielding.

In the above-mentioned first EMI shielding method, it is necessary to form a single package structure 10 first, and then assemble the metal cover 14 to the respective package structures 10 one by one, so the process procedures are quite complicated. In the above-mentioned second EMI shielding method, it is necessary to perform wire bonding for the partial or full chip that needs the EMI shielding, and it is conceivable that the required process steps will be more complicated.

To solve the above-mentioned technical problems, it is an important subject matter to provide a semiconductor package structure, a semiconductor EMI shielding component, and a manufacturing method of the semiconductor package structure with the EMI shielding function, so that the semiconductor package structure has the function of the EMI shielding and simplify the manufacturing process.

For the above-mentioned package structure with the EMI shielding function, two embodiments will be listed below to illustrate the manufacturing method of the package structure with the EMI shielding function.

Please refer to FIGS. 6A to 6C, the first embodiment of a manufacturing method of a semiconductor package structure of the present invention includes steps S01-S05.

As shown in FIG. 6A, step S01 is to provide a package carrier 31, which has a first surface 311 and a second surface 312 opposite to each other, and includes a build-up circuit 313 and a first dielectric layer 314 covering the build-up circuit 313.

Step S02 is to dispose three electronic components 321-323 on the first surface 311 of the package carrier 31. The electronic components 321-323 can be disposed on the package carrier 31 by a wire bonding process, a flip chip process, a reflow process, or a conductive adhesive bonding process, and are electrically connected to the build-up circuit 313.

As shown in FIG. 6B, step S03 is to bond a semiconductor EMI shielding component AM1 to the first surface 311 of the package carrier 31 and cover the electronic components 321-323. Among them, the semiconductor EMI shielding component AM1 is electrically connected to the build-up circuit 313 of the package carrier 31 and electrically grounded. In this embodiment, the semiconductor EMI shielding component AM1 has a support component 34 and a shielding layer 35. The support component 34 can include a plurality of conductive pillars 343 a arranged in the fence type, which can be arranged or fixed on the first surface 311 of the package carrier 31 through the conductive adhesive, and electrically connected to the build-up circuit 313. The shielding layer 35 includes a patterned metal layer 351 and a second dielectric layer 352, wherein, a part of the patterned metal layer 351 is electrically connected to the conductive pillar 343 a.

As shown in FIG. 6C, step S04 is to form a packaging layer 33 in the cavity between the first surface 311 of the package carrier 31 and the semiconductor EMI shielding component AM1 and cover the electronic components 321-323 and the support component 34. In the embodiment, since the support component 34 of the semiconductor EMI shielding component AM1 includes a plurality of the conductive pillars 343 a arranged in the fence type, the packaging layer 33 can cover the package carrier 31 and fill between the semiconductor EMI shielding component AM1, the package carrier 31 and the electronic components 321-323 in a fluid state, and then cured.

Step S05 is to form a plurality of solder balls 36 on the second surface 312 of the package carrier 31. In addition, in the embodiment, the package structure formed by the above steps can be completed by a large-format process (or called a panel-level process), and after the cut-single process, a single package structure with the EMI shielding function can be formed.

It should be noted that, when the support component 34 of the semiconductor EMI shielding component AM1 is the continuous sidewall type, the conductive adhesive can be spaced between the bottom end of the sidewall and the first surface of the package carrier 31, and the packaging layer 33 in a fluid state can be filled between the semiconductor EMI shielding component AM1, the package carrier 31, and the electronic components 321-323 through the conductive adhesive disposed at intervals.

Referring to FIGS. 7A to 7F, the second embodiment of a manufacturing method of a semiconductor package structure of the invention includes steps S11 to S22.

Similar to FIG. 6A of the aforementioned embodiment, step S11 is to provide the package carrier 31. Step S12 is to dispose three electronic components 321-323 on a surface of the package carrier 31.

As shown in FIG. 7A, in step S13, a photosensitive dielectric material is used to form a packaging layer 33 on the first surface 311 of the package carrier 31 and cover the electronic components 321, 322, and 323. Step S14 is to form a plurality of first openings O1 in the packaging layer 33 by a patterned exposure developing method to expose part of the first surface 311 and/or the build-up circuit 313 of the package carrier 31. In the embodiment, the first openings O1 are arranged in a fence type to surround the electronic components 321, 322, and 323 and expose a portion of the build-up circuit 313.

As shown in FIG. 7B, in step S15, a conductive pillar 343 a is formed by electroplating in each first opening O1, so that the conductive pillars 343 a constitute the aforementioned support component 34.

Here, it is to be noted that in other embodiments, the above-mentioned steps S13, S14, and S15 can be replaced as follows. First, the conductive pillar 343 a (the support component 34) is formed on the first surface 311 of the package carrier 31 by patterned exposure developing method and electroplating to surround the electronic components 321, 322, and 323. Next, a packaging layer 33 is formed on the first surface 311 of the package carrier 31 to cover the support component 34 and the electronic components 321, 322, and 323 and expose one end surface of the support component 34. Wherein, the support component 34 is electrically connected to the build-up circuit 313 and electrically grounded. It should be noted that in this example, it is not necessary to select the photosensitive dielectric material as the material of the packaging layer 33, so there are more encapsulation materials to choose from.

Returning to the present embodiment, as shown in FIG. 7C, step S16 is to form a first sub-dielectric layer 3523 on the packaging layer 33 and the conductive pillar 343 a to cover the packaging layer 33. Step S17 is to form a plurality of first sub-openings O2 on the first sub-dielectric layer 3523 to expose an upper end surface of each conductive pillar 343 a.

As shown in FIG. 7D, step S18 is to form a first sub-conductive metal 3511 in the first sub-openings O2 and electrically connect the conductive pillars 343 a.

As shown in FIG. 7E, step S19 is to form a second sub-dielectric layer 3524 on the first sub-dielectric layer 3523 and the first sub-conductive metal 3511 to cover the first sub-dielectric layer 3523. The first sub-dielectric layer 3523 and the second sub-dielectric layer 3524 together form the second dielectric layer 352. Step S20 is to form a plurality of second sub-openings O3 to expose part of the first sub-conductive metal 3511 and part of the first sub-dielectric layer 3523.

As shown in FIG. 7F, step S21 is to form a second sub-conductive metal 3512 in the second sub-openings O3 so that the first sub-conductive metal 3511 and the second sub-conductive metal 3512 form the patterned metal layer 351. Finally, step S22 is to form a plurality of solder balls 36 on the second surface 312 of the package carrier 31.

Similar to the first manufacturing method of the foregoing embodiment, the semiconductor package structure formed in the above steps S11-S22 can be completed by the large-format process (or called the panel-level process). In addition, a single semiconductor package structure with the EMI shielding function can be formed after the Cut-single process.
